It's a very large, complex building facing a lot of problems. For example, it's almost four times the size of the West Block, and you would know as well or better than I the type of sculptural ornamentation and so on.
There are the challenges and complexities of doing a full overhaul where you have structural steel that is losing its structural integrity due to rusting. You have masonry issues, mechanical and electrical systems that are way beyond their life cycle and original to the building, plumbing systems that are original to the building and well beyond their life cycle, and the challenges go on and on.
